But don't we filter out routes we feel we can live without *right now*
without the world ending?

I mean, who accepts prefixes longer than /24 these days anyway?
We've all decided that we "can live without" any network smaller
than 254 hosts and it hasn't made a lick of difference to 
universal reachability.

What's to stop someone who wants to carry around less prefixes from
saying, "Bugg'rit, I'm not going to accept anything smaller than 
a /18"?
